[0002] The design of blades in wind turbines directly affects the conversion efficiency of wind energy and its annual power generation. It is an important part of wind energy utilization. With the development of wind power generation industry, the requirements for blades are getting higher and higher. For blades, stiffness is also a very important indicator. Studies have shown that the stiffness of carbon fiber (CF) composite blades is two to three times that of fiberglass composite blades. Although the performance of carbon fiber composites is much better than that of glass fiber composites, it is expensive, which affects its large-scale application in wind power generation. Therefore, major composite material companies around the world are conducting in-depth research on raw materials, process technology, quality control and other aspects in order to reduce costs. During the transportation of wind blades, it is usually necessary to use brackets to fix them to prevent them from shaking during transportation.

[0003] For example, a transport device for transporting blades of wind power equipment with publication number CN217300771U can only transport one blade at a time. In order to solve the above problem, a bracket for transporting blades is proposed. Utility Model Content

[0010] In a preferred embodiment, a threaded rod is threadedly connected to the interior of the support rod, and an adjustment block is rotatably connected to one end of the threaded rod.

[0011] Through the above technical solution, for wind blades of different sizes, the threaded rod is rotated to move along the support rod, thereby moving the adjustment block out from the inside of the support rod, so that the support rod contacts the outer wall of the wind blade, and the wind blade is fixed inside the fixing frame body, so that the equipment can support wind blades of different sizes.

[0012] In a preferred embodiment, the outer wall of the support rod is provided with a groove matched with the adjustment block.

[0013] Through the above technical solution, the adjustment block can be retracted into the groove in the support rod to prevent it from shaking and causing damage to the outer wall of the wind blade when not in use.

[0014] In a preferred embodiment, the outer wall of the adjustment block is provided with friction patterns.

[0015] Through the above technical solution, the friction between the adjustment block and the wind blade is increased by providing the friction pattern.

[0016] In a preferred embodiment, grooves adapted to the lifting rings are provided on both left and right sides of the bottom of the fixing frame body.

[0017] Through the above technical solution, when two fixing frame bodies are stacked, the groove can accommodate the lifting ring.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are as follows: the utility model provides a bracket for transporting blades.

[0019] During the transportation of wind blades, the fixing frame body is first installed on the transport vehicle, and then the two ends of the wind blade are respectively placed in the two fixing frame bodies, and the blades are supported by the fixing frame bodies. When multiple wind blades need to be transported, the two fixing frame bodies are stacked. At this time, the connecting plate on the lower wall of the fixing frame body at the upper end enters the connecting groove on the upper wall of the fixing frame body at the lower end, and the two fixing frame bodies are locked by the boss and the locking hole to prevent the upper fixing frame body from moving during transportation, so that the bracket can support multiple wind blades.
